| error[E0375]: implementing the trait `CoerceUnsized` requires multiple coercions |
| --> $DIR/issue-26905.rs:16:40 |
| | |
| LL | impl<T: ?Sized + Unsize<U>, U: ?Sized> CoerceUnsized<MyRc<U>> for MyRc<T>{ } |
| | ^^^^^^^^^^^^^^^^^^^^^^ requires multiple coercions |
| | |
| = note: `CoerceUnsized` may only be implemented for a coercion between structures with one field being coerced |
| = note: currently, 2 fields need coercions: `_ptr` (`*const T` to `*const U`), `_boo` (`NotPhantomData<T>` to `NotPhantomData<U>`) |
| |
| error: aborting due to previous error |
